The common effect of probiotics on gut health is the promotion of a balanced gut microbiome. Probiotics consist of live beneficial bacteria that can improve digestive function, enhance nutrient absorption, and help maintain the integrity of the intestinal barrier. They are known to alleviate issues such as diarrhea, irritable bowel syndrome (IBS), and inflammation. Regular consumption of probiotics can also boost immunity, as a healthy gut microbiome plays a crucial role in the body's overall immune response.
